Upper East Side resident Arlene Blatt told Lappin’s office the bikes — both motorized and not — surprise and scare her as they come from varying directions.

“While walking in Manhattan, I’ve felt threatened by reckless electric and standard bicycles that often converge on me from multiple directions,” she said.

Nicholas Viest, who is chair of the Upper East Side’s Community Board 8, said the majority of the quality-of-life complaints the board receives are about delivery bikes.

Making scooters legal

Motorized bikes were made illegal by the city in 2004. But now, some legislators are considering legalizing some of them. Bushwick state Sen. Martin Malave Dilan proposed a bill that would allow certain electric bikes, such as those that can only go 20 mph at their peak speed. But community boards have asked city and state politicians to create stricter restrictions for the bikes, including a proposal that bike operators have licenses and be registered.
